IMPROVEMENT iN GUN-sieurs.

The Schedule referred to in these Letters Patent and making part of the sanne.

To all whom tt may concern:

Be it known that I, FBREDERIC'A. CHURCHILL, of Iittsi'ield, in the county of Berkshire'and State of Massachusetts, have invented a new and useful Improvement'in Sights for Fire-Arms.; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being Vhad to the accompanying drawing forming part l'of this specification, in whch- Figure l represents a face view of my improved sight. I

Figure 2 is a face view of the front sight or bead. Figure 3 is a transverse section through the sight. Figure 4 is a vertical section through the bead. Similar letters of reference indicate corresponding parts. l This invention relates to a new construction of sights for lire-arms of all-kinds, both in front and rear.

'.lhe front sight or bead A. is made tubular, and has two or more pins, a a, projecting convergingly from the inner 'surface of the tube toward but not quite to the center; thereby the centeris not only properly indicated, but the object to be viewed is, by the pins, divided, and its position made clear to the eye, as well 1ateral groove of the gun, and laterally adjustable thereon.

I he rear sight O is-made in form of a vertical slide, guided on a slotted post or plate, D, that projects from the barrel or stock.

which is secured to a'piu hung in the post l1)', and provided with a milled wheel or handle, b.

By turning the cam E the slide will be` raised or lowered at wi-ll'and its aperture c set at the desired position` 't Thefnce of the wheel b may be divided r marked, so that the marksman may, from the marks, be enabled to know f or which. distance the sight has been set.

A suitable Clamp, friction device, or pawl, may be used to hold the cam in any desired position.

Having thus described my invention, 'l claim' as new and desire to secure Patent- 1. The bead or front sight-A, composed of the tube and two or more convergent pins, substantially as by Letters herein shown and described.

2. The perforated sight C, made vertically adjustable by the cam E, as shown and described.
